SPECIFICATION forming part of Letters Patent No. 292,.25, dated January 22, 1884.

' Application filed November 8, 1883. (No model.) 7

Be it known that 1, CHARLES D. LATHRoP, a citizen of the United States, residing at Newark, in the count-y of Essex and State of New Jersey, have invented new and useful Improvements in Umbrella-Frames, of which the This invention relates to that class of umbrella-frames in which two sets of stretchers are combined with the ribs; and it consists in the novel construction and arrangement of parts hereinafter described.

In the accompanying drawings, Figure 1 is, a sectional view of an umbrclla-frame embodying my invention, showing the position of the parts when the umbrella is opened.

closed. Fig. 3 is a detail View of one of the stretchers, showing its appearance in blank form. Fig. 4: is a similar view thereof when brought into shape. Fig. 5 illustrates a modification.

Similar letters indicate corresponding parts.

The letter 'A designates the umbrella-stick supporting the crown-ring B, to which are jointed the ribs 0, in the usual manner.

The letters D Eindicatc thetwo sets of stretchers, one of which I denominate the main stretchers and the otherthe supplemental stretchers, and F denotes the runner. The main stretchers D are jointed to the ribs '0 and runner F at the upper and lower ends, and the supplemental stretchers E are jointed to the ribs at the upper end, while they are constructed to engage the main stretchers at the lower end, as bymeans of an eye or loop, G, so that such end of the supplemental stretchers is movable on the main stretchers. The point at which the supplemental stretchers E are jointed to the ribs is abovethat at which the main stretchersD are jointed thereto; and the length of the supplemental stretchers is such that when the umbrella is opened of the main stretchers, as shown in Fig. 1, whereas when the umbrella is closed such eye or loop takes an intermediate position, as shown in Fig. 2, and-hence the supplemental dition of the umbrella. \Vhen the umbrella I is opened, the ribs are sustained by the supplemental stretchers as well as the main stretchers, due to the fact that the eye or loop G is then substantially immovable, the runner F preventing downward movement, and the main stretchers, by their angles or positions,

' preventing upward movement thereofa When the umbrella is opened, the supplemental stretchers E are supported on the runner F by means of a shoulder, I, at the lower end of such stretchers, this shoulder occupying the proper position to take its place on the runner, as shown in Fig. 1, and consequentlythe main stretchers are entirely relieved from the weight of the supplemental stretchers. The eye or loop G and shoulder I are integral with the supplemental stretchers, they being produced by flattening the stretchers at the proper end, then making a slit of approximately U shape in the flattened part, as at s, Fig. 3, and then bending the parts within and without the slit in reverse directions, one part constituting the eye or loop and the other part the shoulder, and by this means a light and durable article is obtained at a low 7 5 cost of manufacture. The loop or eye G, however, may also be separate from the stretchers, in which case the stretchers may be pivoted thereto, as shown in Fig. 5. Said eye or loop, moreover, may be arranged-to work on the umbrella-ribs, in which case both sets of stretchers are jointed to the runner, and a suitable stop is used to regulate the mo tion of the eye or loop. The supplemental stretchers E may also be connected to the ribs 8 5 ata point below the main stretchers, as shown in Fig. 6, in which case the eye or loop G moves in a reverse direction, and a stop is used on the main stretchers to regulate the position of the supplemental stretchers when 0 the umbrella is opened.

Vhat I claim as new, and desire to secure by Letters Patent, is

1. The combination, substantially as here inbefore described, of the ribs, the runner, the 5 main stretchers, having the ends jointed to the ribs and runner, respectively, and the supplemental stretchers, having one end jointed to the ribs at a point above the main stretchers, and the other end constructed to engage the main stretchers. 1

2. The combination, substantially as here- 5 inbefore described, of the ribs, the runner, the

main stretchers, having the ends jointed to the ribs and runner, respectively, and the supplemental stretchers, having one end jointed to the ribs and the other end constructed with 10 an eye or loop to engage the main stretchers,
